Wind speed increases rapidly with height and becomes less turbulent. Rather, the real problem is that the gas will have to be helium or hydrogen, and bother are problems. Helium is about to run out and is already fairly expensive. Hydrogen is flammable, requires a lot of energy to generate by electrolysis, and diffuses quickly out of most flexible materials. My guess is that most wind power will be generated from offshore floating wind turbines that are 100 km out at sea, and outside the visible range for most people.
